Subject[PATCH v4 0/2] mm: using CMA for 1 GB hugepages allocation
Date
The patchset adds a hugetlb_cma boot option, which allows
to reserve a cma area which can be later used for 1 GB
hugepages allocations.

This is v4 of the patch(set). It contains a patch from Aslan,
which adds a useful function of the cma side, and the previous
version of the hugetlb_cma patch (v3) with all following cleanups
and fixes squashed, plus the following changes:
1) removed the hard-coded archs list from docs
2) added a warning printing on non-supported archs
3) hugetlb_lock is temporarily dropped in update_and_free_page()

I've retained Michal's and Mike's acks, because changes are
not significant. Please, let me know if there is something
wrong.

Thanks!
